Quick answerThe soil survey shows low shrink-swell soil at nearly every spot we checked in North Charleston, so swelling clay is not the usual cause. Water is the bigger clue. Several mapped spots have a water table at or near the surface. Wet ground, settling and fill are the first things to check. An inspection shows what is happening at your home.

Foundation Help in North Charleston, SC

Foundation Pros of Charleston helps with foundation repair in North Charleston by finding the cause of cracks, sticking doors and sloping floors. The city has homes of many ages. By Census estimates, about 46 in 100 were built before 1990 and about 26 in 100 since 2010.

Water is worth checking first in any foundation repair in North Charleston. Parts of the city sit on wet, poorly drained ground, as the soil facts below show.

What the Ground Looks Like in North Charleston

We checked the federal soil survey (USDA NRCS) at 24 points spread across North Charleston. At 9 of them the survey lists "urban land", which is ground that has been built over and is not described in detail. Two points were open water.

At the 13 points with natural soil, 7 were poorly or very poorly drained. At 3 points the survey puts the yearly high water table at the surface. Three points carry an "occasional" flood rating, and one carries "very frequent".

Shrink-swell was low at every point but one. That one, a very poorly drained and often flooded spot, rated high. So the survey points to water more than to swelling clay.

A point is not your lot, and soil changes from block to block. You can look up your address on the Web Soil Survey. NOAA's tide gauge in Charleston Harbor, not in North Charleston itself, shows sea level rising about 1.4 inches every ten years.

If water is the cause, drainage and water control or crawl space encapsulation and vapor barriers may be part of the fix.

North Charleston Neighborhoods

The Census Bureau's American Community Survey (2024 one-year estimates) counts 61,674 homes in North Charleston. The middle home was built in 1995. About 46 in 100 went up before 1990, and about 26 in 100 in 2010 or later.

About half of occupied homes are owned and about half are rented. About half of all homes are single-family houses, and about 1 in 20 is a mobile home.

The Census does not say what kind of foundation a home has. Slab, crawl space and pier homes all need a look in person. These numbers are estimates with a margin of error.

Our 5-Step Process in North Charleston

  1. Call or send the form. Tell us your address and what you see. A contractor reviews it and sets up a visit.
  2. Walk the house and the lot. The inspection looks inside and out. Gutters, grading, water around the house and the crawl space or slab all get a look.
  3. Match the cause to the fix. Wet ground, settling and fill call for different foundation repairs. The contractor explains the options in plain words.
  4. Review the written scope. You see the work in writing before you agree. Ask any question about it.
  5. Repair and final check. The contractor does the work and checks it with you. If a permit applies, the office that covers your address handles it.

Foundation Questions in North Charleston, SC

Which office covers my North Charleston address?

Census maps show parts of the city in both Charleston and Dorchester counties. The city pages do not say which addresses each office covers, so call the city office first. The table above lists all three offices.

Do I need a permit for foundation work in North Charleston?

It depends on the work and the address, and we cannot say for you. Ask the office that covers your address. The contractor's written scope lists the work you can describe to them.

Does a high water table hurt a foundation?

It can. Wet soil can soften the ground under a footing, and moisture can reach a crawl space. The soil survey shows shallow water tables at several sampled points in the city, and an inspection shows whether your lot has the problem.
